The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - slip: bound decode() reads against the compressed packet length slhc_uncompress() parses a VJ-compressed     TCP header by advancing a pointer through the packet via decode() and pull16(). Neither helper bounds-     checks against isize, and decode() masks its return with & 0xffff so it can never return the -1 that     callers test for -- those error paths are dead code. A short compressed frame whose change byte requests     optional fields lets decode() read past the end of the packet. The over-read bytes are folded into the     cached cstate and reflected into subsequent reconstructed packets. Make decode() and pull16() take the     packet end pointer and return -1 when exhausted. Add a bounds check before the TCP-checksum read. The     existing == -1 tests now do what they were always meant to. (CVE-2026-45843)

Note that Nessus relies on the presence of the package as reported by the vendor.
